Abstract
A system for locating features in image data is provided. The system includes a first component system. The first component system compares first component data, which can be pixel data of a first user-selected component of the feature, to first test image data, which can be selected by scanning image data of a device, such as a die cut from a silicon wafer. The system also includes second component system that is connected to the first component system, such as through data memory locations of a processor. The second component system compares second component data to second test image data if the first component system finds a match between the first component data and the first test image data. The second test image data is selected based upon the first test image data, such as by using a known coordinate relationship between pixels of the first component data and the second component data.
